IMPROVEMENT IN MUD AND WATER DISCHARGES FOR STEAM-BOILERS.

Specification forming part of Letters Patent No. 213,582, dated March 25, 1879; application filed October 24, 1877.

To all whom it may concern:

Be it known that we, THOMAS MGILVAIN and WILLIAM SPIEGEL, of the city of Oincinnati, county of Hamilton, and State of Ohio, have invented new and useful Improvements in Mud andWater Discharges for Steam-Boilers; and we do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

Figure 1 represents a perspective view of the section of the boiler with the current plate in side and the discharger below, with the discharge-pipe underneath. Fig.2 represents a view of the irlangev at the top of the discharger. Fig. 3 is a view of the bottom plate of the discharger.

The nature of our invention consists in the combination of an oval current-plate, as constructed inside of the boiler, with a conical discharger (wider below than above) and disch arge-pipe underneath the boiler.

The object of our invention is to take the mud or sediment of water direct frbm any boiler, where there may be a series or any number of boilers, so that the mud or water may be taken away from any one of the boilers.

A represents a section of the lower part of a. boiler, with one or more flues, B, and its manhole or hand-hole O. D is the current-plate, made oval, and is connected or fastened to the boiler by bolts or rivets. There is an open space between the plate D and the boilershell A, to allow the current of water to conduct the mud to the discharger E below. As the water and mud pass in a current under the plate D, they enter the circular aperture G and fall into the discharger E. The discharger E is cone-shaped, with a hand-hole, H, and a circular bottom plate, J, that is convex below, and having an aperture, K, in the center, as shown at Fig. 3, where the discharge-pipe L is connected, to blow ofi the mud, sediment, or water when required. The discharge-pipe L has an ordinary stopcock, M, to allow the carrying 011' of the mud, sediment, or water (whenever required) direct from the boiler.

What we claim as our invention, and desire to secure by Letters Patent, is

The combination of the current-plate D in the boiler A and the conical mud and water discharger E beneath the boiler A, with its discharge-pipe L, when constructed as herein described, and for the purposes set forth.
